Constitution of CanadaThe Constitution of Canada (Constitution du Canada) is the supreme law in Canada. It outlines Canada's system of government and the civil and human rights of those who are citizens of Canada and non-citizens in Canada. Its contents are an amalgamation of various codified acts, treaties between the Crown and Indigenous Peoples (both historical and modern), uncodified traditions and conventions. Canada is one of the oldest constitutional monarchies in the world.
Philosophy of lawPhilosophy of law is a branch of philosophy that examines the nature of law and law's relationship to other systems of norms, especially ethics and political philosophy. It asks questions like "What is law?", "What are the criteria for legal validity?", and "What is the relationship between law and morality?" Philosophy of law and jurisprudence are often used interchangeably, though jurisprudence sometimes encompasses forms of reasoning that fit into economics or sociology.
Constitutional economicsConstitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics.
ConstitutionalityConstitutionality is said to be the condition of acting in accordance with an applicable constitution; the status of a law, a procedure, or an act's accordance with the laws or set forth in the applicable constitution. When laws, procedures, or acts directly violate the constitution, they are unconstitutional. All others are considered constitutional unless the country in question has a mechanism for challenging laws as unconstitutional.
Constitutional courtA constitutional court is a high court that deals primarily with constitutional law. Its main authority is to rule on whether laws that are challenged are in fact unconstitutional, i.e. whether they conflict with constitutionally established rules, rights, and freedoms, among other things. Prior to 1919, the United States, Canada and Australia had adopted the concept of judicial review by their courts, following shared principles of their similar common law legal systems, which they, in turn, had inherited from British legal practice (the United Kingdom does not have a codified constitution and judicial review of primary legislation is prohibited).
